2.6. escsConsole

The console machine is directly connected to a monitor in the control room and is intended to be used by observers in order to run auxiliary observation tools such as quicklook the Imager and the ScheduleCreator. Configuration files can be found on the svn repo at:

http://svn.med.ira.inaf.it/repos/escsconf/escsConsole

The machine main configuration parameters are the following:

PARAMETER	VALUE
hardware	ERack E4 computer engineering
Kernel	2.6.18-128.1.1.el5 x86_64
hostname	escsConsole
eth0	192.168.1.54
eth1	192.167.189.54

2.6.1. OS installation

2.6.2. IDL

This is the only machine running IDL 8.2 in this setup. IDL is installed via original CD-ROM available at Medicina station and install location is the one suggested by default:

/usr/local/exelis

We then created a directory for IDL third party libraries in:

/usr/local/idllib

and installed there Coyote and astron libraries. You can find original versions of the libraries at the following links:

• http://www.idlcoyote.com/programs/zip_files/coyoteprograms.zip
• http://idlastro.gsfc.nasa.gov/ftp/astron.tar.gz

Remember to add th edirectory to the IDL path and to include all subdirectories recursively, the easiest way to do that is via idlde->window->preferences.

2.6.2.1. update from June 2017

In 2017 IDL switched vendor and thus a major update has been performed to the 8.6 version. Unfortunately this version breaks compatibility with OS version in use on escsConsole and cannot be installed on this machine.

In order to enable a legacy license for the 8.2 version currently in use, IDL now conects to a license server centrally managed by INAF. The path to the server is defined in an environment variable defined in:

$ less /etc/basrh
...
# LEGACY IDL8.2 LICENSE
export LM_LICENSE_FILE=xxxxx@yyyyyyyy.inaf.it

This enable every user of escsConsole to connect to the license server and have idl correctly working, as identified by the login message of the IDL console:

IDL Version 8.2 (linux x86_64 m64). (c) 2012, Exelis Visual Information Solutions, Inc.
Trial version expires on 31-mar-2018.
Licensed for use by: INAF - Licenza test server centrale

2.6.3. SDI and Quicklook

The Single dish imager can be downloaded from the SRT scicom wiki page at http://scicomsrt.pbworks.com/w/page/54294508/IMAGING%20ANALYSIS and has been extracted to the same location in:

/usr/local/idllib/SDI

SDI has ds9 as a dependency, which can be download from http://hea-www.harvard.edu/RD/ds9/site/Download.html or you can find in /root/software/ directory. Extract ds9 and copy it in:

/usr/local/bin

You can find the fits_look.pro idl procedure in /root/software directory. The procedure has been copied in /usr/local/idllib/ as the rest of custom idl programs.

2.6.4. Python

EscsConsole is provided with Python2.7 installed. This allow users and astronomers to use and develop data analysis programs based on more recent technologies then the default Python2.4. Installing is easy, just remember to do a make altinstall instead of the usual make install:

[root@escsConsole /root/software/] wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
[root@escsConsole /root/software/] tar xzvf Python-2.7.6.tgz
[root@escsConsole /root/software/] cd Python-2.7.6
[root@escsConsole /root/software/] ./configure
[root@escsConsole /root/software/] make
[root@escsConsole /root/software/] make altinstall

After this step you can invoke python2.7 from command line. Using this python version Download and install the latest version of python-setuptools from https://pypi.python.org/pypi/setuptools and then:

[root@escsConsole /root/software/] easy_install-2.7 pip
[root@escsConsole /root/software/] pip-2.7 install ipython numpy astropy

Warning

Installing with normal make install will override system python installation causing serious problems. Beware!

2.6.5. GPFS

Installing GPFS on escsConsole requires some additional work due to the 64 bit OS, this leads to different dependencies and configuration parameters:

[root@escsConsole /root/software/gpfs/]# yum install kernel-devel kernel-headers
[root@escsConsole ~]# cd /root/software/gpfs
[root@escsConsole gpfs]# yum install compat-libstdc++-33-3.2.3-61.i386
[root@escsConsole gpfs]# yum install compat-libstdc++-33.x86_64

You may start the GPFS GUI now by typing : /etc/init.d/gpfsgui start
Alternatively, the GPFS GUI will start on reboot.

[root@escsConsole gpfs]# cd /usr/lpp/mmfs/src/config
[root@escsConsole config]# cp site.mrc.proto site.mrc
[root@escsConsole config]# vim site.mrc

//SET THE FOLLOWING PARAMETERS IN THE FILE

We added this node to the gpfs cluster after the cluster itself had been created and initialized, so we follow here with the necessary instructions used to add a node to the escsCluster. So login into the master node and:

[root@escsMaster escsCluster]# mmaddnode escsConsole
